To answer the questions:
Electrically, I connected an actual Apple-branded 9-pin to 25-pin (aka "modem") cable to a 25-pin female-to-female adapter to a 25-pin to 9-pin PC cable. No null modem adapter. (I originally made the mistake of trying to use a PC-style RS-232 serial cable instead of the Apple-branded one, but that didn't work, and the instant I added a null modem, the Mac would go into a freakout power cycle loop. Then I looked up and discovered that Apple's RS-422 serial is a different pinout than PC RS-232, and remembered I had the Apple-branded cable that was probably wired the right way.)

I'm going to have to ask you to get put a multimeter to that thing at some point so we can get some pinout data! (I am totally making evil plans right now.) }
